UNLABELLED The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity caused by conventional medications as well as herbals and dietary supplements (HDS). To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The(More)
Welcomed and exciting results from three large, controlled trials of different regimens of oral antiviral agents for chronic hepatitis C, genotype 1, have now been published in the Journal.1-3 The regimens all included the combination of ledipasvir and sofosbuvir, two new direct-acting antiviral agents with potent activity against hepatitis C virus (HCV).(More)
IMPORTANCE Biliary atresia is the most common cause of end-stage liver disease in children. Controversy exists as to whether use of steroids after hepatoportoenterostomy improves clinical outcome. OBJECTIVE To determine whether the addition of high-dose corticosteroids after hepatoportoenterostomy is superior to surgery alone in improving biliary drainage(More)
BACKGROUND Acute liver failure (ALF) is a rare syndrome of severe, rapid-onset hepatic dysfunction-without prior advanced liver disease-that is associated with high morbidity and mortality. Intensive care and liver transplantation provide support and rescue, respectively. OBJECTIVE To determine whether changes in causes, disease severity, treatment, or(More)
OBJECTIVES To examine the medical status of children with biliary atresia (BA) with their native livers after hepato- portoenterostomy (HPE) surgery. STUDY DESIGN The Childhood Liver Disease Research and Education Network database was utilized to examine subjects with BA living with their native livers 5 or more years after HPE and to describe the(More)
UNLABELLED Hepatitis C virus (HCV) infection typically results in chronic disease with HCV outpacing antiviral immune responses. Here we asked whether innate immune responses are induced in healthcare workers who are exposed to small amounts of HCV, but do not develop systemic infection and acute liver disease. Twelve healthcare workers with accidental(More)
Little is known about the molecular interactions required for hepatitis C virion assembly. The 5' noncoding region (5'NCR) of the RNA genome is highly conserved and has extensive secondary structure. The highly basic core protein is rich in arginine and lysine residues. We postulate that a specific interaction between these structures may be important for(More)
A 51-year-old woman deve loped a sensorimotor periphe ral neuropathy and a systemic vasculitis secondary to hepatitis C-related essential mixed cryoglobulinemia. Therapy with inte rferona (IFNa ) at 3 million units three times a week was initiate d. While on interferon, the clinical features of cryoglobuline mia progre ssed rapidly and the patient(More)
Fifty years ago, only a quarter of infants born with congenital heart disease (CHD) survived beyond the first year of life. It has been estimated that 80% to 85% of patients can expect to reach adulthood. Today, there are close to 1 million adults living with CHD in the United States alone. Since its introduction, the Fontan operation has become established(More)
Studies on hepatitis C virus (HCV) replication have been greatly advanced by the development of cell culture models for HCV known as replicon systems. The prototype replicon consists of a subgenomic HCV RNA in which the HCV structural region is replaced by the neomycin phosphotransferase II (NPTII) gene, and translation of the HCV proteins NS3 to NS5 is(More)
